Spinal Arteriovenous Malformations

Spinal line arteriovenus mutations involve 20% to 30% of all spinal vascular malformations.The angioarchitecture at the move from supply route into vein can be either through a system (the nidus) or direct (ie, fistulous).2,3 Fistulous AVMs are found externally and just seldom have intramedullary compartments and are along these lines generally called perimedullary arteriovenous fistulas.

Your medulla spinalis uses chemical element from the blood in your capillaries, and this oxygen-depleted blood then passes into veins that drain blood from your medulla spinalis to your heart and lungs. in an exceedingly spinal AVM, your blood passes directly from your arteries to your veins, bypassing capillaries. This disruption in blood flow causes cells in your spinal tissues to deteriorate or die.

The arteries and veins in an exceedingly spinal AVM will rupture, which ends in harm within the medulla spinalis (hemorrhage). Sometimes, the AVM enlarges and compresses the medulla spinalis. Spinal AVM will go unknown unless you start experiencing signs and symptoms. The condition is treated with surgery to halt or presumably reverse a number of the spinal harm.
